Definitions

  • the present invention relates to a mortising machine.
  • a mortising machine which is formed as a hand-held machine and has a base plate to be arranged on a surface of a workpiece to be machined, a mortising tool arranged to penetrate into the workpiece to remove chips and extending through an opening in the base plate so as to produce a groove-like recess in the workpiece during displacement of the mortising machine, and a chip removing device provided with a suction opening in the area of the opening of the base plate.
  • the dust removing device sucks out the milled chips directly around the mortising cutter. But it is not possible also to completely remove the chips deposited in the mortise groove--at any event, with the conventional suction line.
  • one feature of the present invention resides, briefly stated, in a mortising machine, in which the chip removing device, in addition to the first suction opening, has also a second suction opening, spaced from the first suction opening and open out in the area of a mortising recess at the workpiece.
  • the mortising machine When the mortising machine is designed in accordance with the present invention, almost all chips can be removed via a second suction which extends close to the mortise groove and in particular is equipped with a deformable body reaching into the groove.
  • the deformable body prevents the chips from exiting through the mortised groove and dams up the milled material. This has the advantage that the dammed up chips can be sucked out via the second suction opening in a closed manner.
  • the second suction opening is provided with a deformable body, which can be formed as a broom, projecting forward in the manner of an apron and insertable into the mortised recess so as to hold back the milled chips in a sealing manner.
  • the deformable body as a broom which is arranged at the rear wall of the second suction opening so as to be adjustable with respect to height and can be inserted into the mortised groove up to the base is particularly advantageous.
  • a profile particularly a saw tooth profile, can be arranged in a rear wall of a suction connection piece of the chip removing device, so that the broom is insertable in the profile in a plurality of positions.
  • the multiplestepped sawtooth profile in the rear wall of the suction opening is simple to produce and enables a simple operation of the height adjustment.
  • the broom is easily exchangeable.
  • the suction connection piece with the second suction opening is connected with the chip removing device in a simple manner in that it is detachably clamped at a tubular central part of the suction device by means of two elastic clamping arms which are connected in one piece with the suction connection piece.
  • FIG. 1 shows a longitudinal section through the base plate of a mortising machine and a dust removing device
  • FIG. 2 shows a cross section according to line II--II in FIG. 1.
  • a known hand-held mortising machine which is constructed as a recessing and shaping machine 1, substantially has a base plate 2 and a motor housing 3 which are connected with one another via columns 4 so as to be adjustable with respect to height.
  • a mortising tool 5 which engages through an opening 6 in the base plate 2 projects out of the motor housing. The tool 5 cuts a recess or mortised groove 8 into a workpiece 7 in rotary movement.
  • a chip removing device 10 is fastened at the base plate 2 of the mortising machine 1 by means of screws or catch locks, not shown.
  • the device 10 has a bell-shaped first suction piece 11 located above the opening 6.
  • the first suction piece 11 is open at the bottom and has, at the upper side remote of the base plate, an opening 12 for the passage of the mortising tool.
  • the suction piece 11 passes into a connecting piece 13 which leads diagonally upward.
  • a central part 14 having a circular, tubular cross section and an axis lying parallel to the base plate 2 adjoins the connection piece 13.
  • the central part 14 has a broad, flat annular groove 15 at its tubular exterior end an opening 16, which is rectangular in the embodiment example and arranged in the area of the flat annular groove 15 on the side facing the workpiece.
  • a suction connection piece 18 is fastened at the central part 14 in such a way that two bent clamping arms 19, 20, which are formed on at the suction connection piece 18, enclose the central part 14 and reach into the flat annular groove 15 (see FIG. 2). They are held there by clamping force.
  • the clamping arm 19 has two actuating elongations 21, 22 at its free end, and the clamping arm 20 has one actuating elongation 23.
  • the actuating elongations intersect one another in the manner of shears.
  • the suction connection piece 18 has a passage 24 at the top and a suction opening 25 at its lower end.
  • the suction opening 25 can be placed against the workpiece 7 and lies on the same plane as the base of the base plate 2.
  • This second suction opening 25 has a rear wall 26 of increased thickness compared to the first suction piece 11.
  • a twosided sawtooth profile 27, which is open at the bottom and the sides, is worked into the rear wall 26 transversely relative to the axis of the central part 14 in the manner of a slot.
  • a broom 28 has a haft 29 with a profile 30 corresponding to the profile 27 and reaches with its bristles, to the base of the groove 8 mortised into the workpiece 7.
  • the broom is inserted into the sawtooth profile 27.
  • the connection piece 18 and the broom 28 are at least as wide as the maximum groove width which can be produced with the mortising machine.
  • the chip removing device 10 can be removed from or inserted into the base plate 2 as required.
  • the broom 28 Prior to the commencement of the mortising work, the broom 28 is fastened in such a way in the rear wall 26 by means of lateral insertion at the height of one of the steps of the sawtooth profile 27 that the bristles of the broom reach until the base of the groove 8.
  • the broom 28 is inserted into the mortised groove 8 and engages in it.
  • the milled chips which are not sucked up via the first suction opening 11 and still remain in the groove 8 are prevented from exiting via the groove 8 by means of the broom 28.
  • the chips are sucked up via the suction connection piece 18, the passage 24 and the opening 16 via the central part 14 and the suction connection piece 17.
  • the clamping arms 19, 20 are spread by means of pressing together the actuating elongations 21, 22, 23 and rotated in the annular groove 15.
  • the connection piece 18 is now set away to the side and the opening 16 is closed by means of one of the clamping arms 19, 20.
  • the suction connection piece 18 can also be entirely removed, e.g. for cleaning purposes, by spreading apart the clamping arms 19, 20 by means of vigorously pressing together the actuating elongations 21, 22, 23 until the clamping arms 19, 20 can be removed from the annular groove 15.
  • the second suction opening can also be worked directly into the base plate of the mortising machine or can comprise a duct which is completely separate from the suction duct of the first suction opening.
  • the broom can be fastened at the chip removing device in a desired manner, particularly also by means of screw or snap connections.
  • the broom can also be equipped with rings of some other kind of resilient material instead of with bristles.
  • the sealing function relative to the groove can also be assumed by some other resilient body which adapts itself to the shape of the mortised groove.
